I ATTACHMENT.EOR GAS. STOVES.

Application led- August 8,1921. Serial. No..490,594.

To all whom t may concern.'

*Be Vit known that l, ERNEST A. HORN- Bos'riiL, a citizen ofthe United States, and resident of Des Moinesfin kthe county of Polk and .State of Iowa, have invented a certainv new` and .useful Attachment for GasStoves, of which the lfollowing is a speciication vThe. obj ecti of` my...invention` is yto provide a simple, durable and vinexpensive .device in the. nature of anattachment whichmay; be

a applied toigas stovesin such aA manner that 'the heat that is ordinarily wastedby heatving the contents of a vessel overa4 'giverl burner may be directed to another vessel for the purpose ofkeeping the contents of. the

Ysecond vessel warm, or for slow cooking.V

A further. obj ect isto .provide in adevcie abovev mentioned, a detachable. yheat modifying device between the flamesfofa burner from which the heat is derived andthe vesrelative to each other insuch amanner that i they. may be easily separated for cleaning.

VThese and other objects will be apparent .f

to those skilledin the; art.

My invention vconsists .in the construction, arrangement andcombination of the various pai'tsof the device, whereby the objects .contemplated are attained, as'hereina-fter more fully set forth, pointedr out inv my claim, and `illustrated inthe accompanying drawings, in which:

VFigure 1 is a plan view of my improved device.

Figure 2 is a longitudinal sectionaly view takenv onthe line 2-2 of Figure 1.

Figure 3 is a det-ail sectional view taken on the line 3-3 ofv Figure 1.

Figure 4 is a perspective view of the heat defiector plate. Figure 5 is an end-.elevation showing Ithe upper and. lower platesin aseparatediposition.

My improved device comprises a bottom plate having end members l1 and side .members 12, the said plate being formed of member, 10.

- Each of the end members 11y isprovided with a. series of depressions 13 which extend inwardly. The Amember 10 is provided with an opening 14. near one end andcentrally between itssides. fllhisropening has its edges provided with aslightly upwardly. turned flange 15'.

A top plate 16 is alsoprovided having a seriesof end members 17, and side members 18, said end members 17 being provided with a series of inwardly extending depressions 19. The said side and end members 17 and 18 are so arranged that they will telescopically receive the side and end members 11 and 12 of the plate 10 with the depressions 19 within the depressions 13, as clearly shown in Figure 2.

rl`his provides means whereby the two plates may be easily and quickly separated from each other when it is so desired for ithe purpose of cleaning and so forth.

lWhen the plate 16 is'in position relative to the plate 10, the `two plates are substantially parallel with each other.

rPhe member 10 is designed to rest on the top of agas stove or similar heating device with the opening ltimmediately above one of thejgas burners, which is designated in thev drawings by the numeral 24, in such a manner that the heat from the burner will pass upwardly through the opening 1li into the interior of the chamber between the plates 10 and 16.

The plate 16 is provided at one end with an opening-2O and. at the opposite end with an opening 21, the opening 2O being designed tor rest centrally above the opening 14 of the plate 10.

The plate 16 is provided with a series of depressions 22 which are preferably pressed inthe metal, and radiating from the opening 20. The depressions 22 form a-series of downwardly extending Hanges on the under face of the plate16, and serve to reinforcev the said plate against buckling due tothe weight ofthe kcontainer above7 and also against buckling due to the uneven eX- pansion lof the plate 16, du-e .to theflame hereinafter to. be described.

.-Arranged.in:a circular manner and between each of the depressions 22, I have provided an opening 23 which is to permit the heat from the burner to be conducted to a container 25 above the said op-enings and23.

The top of the plate 16 at the point where the openings 20 and 23 are provided is designed to be perfectly smooth with the exception of the grooves 22, so that the bottom oi the container will rest against the top of the plate 16.

lThe top of the plate 16 adjacent to the opening '21 is provided with a series of upwardly extending flanges 26 radiating from the said opening. These flanges are for the purpose of holding the container 27 a slight distancev above the plate 16, and also to reinforce the said plate 16, and `to prevent the-samefrom buckling due to uneven temperatures, the flanges 26 being formed by pressing the metal upward which leaves the grooves 28 on the under surface.

The space between each of the flanges 26 .is provided with an opening 29 similar to the opening 23, and are for the purpose of permitting heat within the chamber to pass upwardly between the flanges 26 and beneath I have provided a device which may be placed above the gas stove `with the openings 11 above oneot the burners in .such a manner that the heat from the said burner will strike the ends 17 at a point below the container 25, and a large amount of the said heat will be radiated and conducted to they bottom of said container, part of it through the opening 23 and part of it through the top member 16. It is a well known fact that in order to supply combustion to the gas iiames, that a large amount of air must be supplied to the y flames, which has to be circulated beneath the bottom of the container being heated. This hot air is conducted between the plates 10 and 16 and out through the yopenings 21 and 29 so as to be brought into engagement with the bottom of the container 27 Further heat will then be Given to thebottom of the container' 27 which would otherwise go to waste by the hot air passing up around the sides of the container 25, if the said con tainer 25 is placed immediately above the gas burner as is commonly practiced in the ordina-ry gas stoves.

Thus is will be seen that T have provided means which will utilize a large per cent of heat which is usually wasted and carried away by the gases of combustion, in order to provide against heat -from the burner 24.- striking the bottom of the container 25 directly, and thereby burning certain things which may be cooking within the container,l

such as preserves, jellies, and so forth.

I have PIOVded 2L disk 30 which is formed with a number of laterally 'extending legs 31 from one of its faces. These legs are pref erably formed by being cut out of the said disk and then being bent laterally.

The disk 30 is of such a size and diameter that the legs 31 may be placed on the member 10 at a point just outside of the flange 15. The said legs are of such length that the plate 30 will rest substantially midway between the plates 10 vand 16, as clearly shown inFigure 2.

This member 30 may be placed in position when so desired by first removing the plate 16 from the plate 10. After the said memp edges of the plate 30 and a portion of it will be radiated through said plate and also through the bottom of 'the container'25, and slow cooking within the container maybe accomplished without burning the same.`

One of the advantages of my improved device lies in the fact that the plates 10 and 16 may be separatedfrom each other for the purpose of cleaning between them. This is easily accomplished by placing the fingers of one hand in the hole llfand those of the opposite hand in some of the holes 23 and pulling the two members apart. The spring in the members 17 and 11 is sufficient to yieldingly hold the .members 19 within the members 18. p

Another advantage of my construction lies in the fact that the. downwardly extending ribs 22 and the ribs 26 are exactly the same, except one is pressed downwardly while the other is pressed upwardly.k Both of these openings may be formed with a single die, the plate 16 being turned over after one set of openings have been formed.

I claimv as my invention:

A heater'attachment for gas stovesv comprising upper and ,lower plates, each of said plates being provided with side land. end members, the side vand end members of one plate being designed to telescopically receive the-,side and end members of the opposite plate, a plurality of openings in the top member and an opening in the bottom member, the opening of said bottom Amember being opposite from one oi. the openings of said top member, the opening of said bottom member being provided with an up wardly extending annular flange, a circular defiector plate having'v a ,f series of downwardly extending legs, the legs of said plate being designed to detachably restoutside of the side of said annular flange said defiector plate being spaced midway between and parallel with the said upper and lower plates.
